Hi Mathsguru


Sorry but this is just P2 maths question but I am not sure how to present the workings.


Question 1.

Cheryl and David work in the same building.
Cheryl is on the 18th floor.
David is on the 29th floor.
How many floors are in between them ?

( I would actually just count from 19 to 28 th floor as answer 10 but not sure if there is a proper way to present the answer)



Question 2

Study the pattern and put in the missing number.

What should the answer be ?

If P2, answer should be:

1.11 floors
2. 55

An easy way to remember is the difference between the floors is the higher floor minus the lower floor minus one. In this case, the answer is 28-19-1 = 10 floors

It is the 1st row number minus the second row e.g. 30-25=5, 70-20=50, so 100-45=55

Hope I helped!

Hi chiclil,

My solution:

Question 1 (base on 18th floor to 29th floor)

Let say 18th floor = 0
so the 29th floor = ( 29-18 ) = 11
Thus from 0 to 11 floor, there are 10 floors in between.

There are 10 floors in between them


Question 2

From the table:
row 1 30 - 5 = 25
row 2 70 - 20 = 50

so 100 - 45 = 55

The answer is 55.

Thanks for the explanations, again, small! You and BigDevil could be the next Mathsguru!

I have a question here:


If the question never states to leave the answer as fraction/mixed number or decimal, can the child leave the answer as a decimal and still get it correct?

For example, the child writes the answer as 6.66667 = 6.67. The answer is
6 2/3.

This is for a question in Paper 2 btw. Thanks in advance

Hi worldangle,

My opinion is 6 2/3 will be good enough and sufficient and yet the kid not need to spend more time.

Even if you chose to leave as a decimal, should write 6.67 (correct to 2dp).
